This is actually in the works: https://iceberg.apache.org/spec/#default-values This will be part of Spec version 3 that's being finalized.

Are there any examples for Iceberg defaults with V3 for spark-sql or Java SDK? The description makes sense, but not sure what's the format or how to set initial-default from the given link.

Grep for the repo didn't show anything.
